What exactly is your goal when it comes to people around us and investing, is it to have everyone investing, or to have everyone around us not just investing, but investing in bitcoins?
How will you feel if after you try convincing people around you to consider investments especially in bitcoins and they end up investing in another thing not bitcoins?
There are a lot of cryptocurrencies that you can invest in apart from bitcoin and it will be profitable. And it is every investor's wish to see people around them succeed, but it will be very difficult to convince people to invest in bitcoin, because our ways of thinking is psychologically different. The manner I think is far different from the manner people around me think. So some people will find it extremely difficult to understand what you are trying to introduce to them, some people will see it as scam, some people will believe you and some will find it difficult to trust you. If you want to convince people around you to invest in bitcoin you don't have to explain it to them verbally, but you have to show them your achievements in bitcoin investment, if they see the things that you achieved through bitcoin investment, they will be convinced without you trying to convince them.
Also tell them the advantages and the disadvantages of bitcoin investment, inform them about the common risks and profits in it, after doing all these, than let them decide by themselves whether they will invest in it or not. So that even if their investment does not want well they should not blame you, they should have themselves to blame. Because after all they took the decision themselves.
